FIELD OF THE INVENTION

The present invention relates to compounds that can be used to treat orprevent inflammatory diseases or atherosclerosis. The present inventionalso relates to pharmaceutical compositions that can be used to preventor treat inflammatory diseases or atherosclerosis, and to methods oftreating and preventing inflammatory diseases or atherosclerosis. Inparticular, the compounds of the present invention are inhibitors of theenzyme 15-lipoxygenase and are inhibitors of monocyte chemotaxis.

BACKGROUND OF THE INVENTION

Atherosclerosis is a multifactorial disease characterized by excessiveintracellular lipid deposition in macrophages, leading to the formationof foam cells. The accumulation of lipid-loaded foam cells in thesubendothelial space leads to formation of fatty streaks, which are theearly atherosclerotic lesions. Oxidative modifications of lipids,specifically low-density lipoprotein, has been implicated as a majorprocess in foam-cell formation.

Lipoxygenases are nonheme iron-containing enzymes that catalyze theoxygenation of certain polyunsaturated fatty acids such as lipoproteins.Several different lipoxygenase enzymes are known, each having acharacteristic oxidation action. One specific lipoxygenase, namely15-lipoxygenase (15-LO), has been detected in atherosclerotic lesions inmammals, specifically rabbit and man. The enzyme, in addition to itsrole in oxidative modification of lipoproteins, is important in theinflammatory reaction in the atherosclerotic lesion. Indeed, 15-LO hasbeen shown to be induced in human monocytes by the cytokine IL-4, whichis known to be implicated in the inflammatory process.

Inhibitors of 15-LO are especially useful to prevent and treatinflammatory diseases such as asthma, psoriasis, arthritis, andatherosclerosis. While there are several lipoxygenase enzymes, specificinhibition of 15-LO is important in the inflammatory and atherosclerosisprocess. A characteristic feature of atherosclerosis is the accumulationof cholesterol ester engorged foam cells. Foam cells are derived fromcirculating monocytes that invade artery walls in response tohypercholesterolemia, and mature into tissue macrophages. The enzyme15-LO has been implicated in inflammatory disorders and in the originand recruitment of foam cells (See Harats, et al., Trends Cardiovasc.Med., 1995;5(1):29-36). This enzyme is capable of oxidizing esterifiedpolyenoic fatty acids, such as those found in phospholipids. Treatmentof experimental animals with antioxidants which reduced hydroperoxidesproduced by 15-LO has been shown to retard the progression ofatherosclerotic lesions. For example, Sendobry, et al., British Journalof Pharmacology, 1997;120:1199-1206 show suppression of atherogenesis inrabbits fed a high-fat diet and treated with a 15-LO inhibitor.

A therapeutically effective amount is an amount of a compound of thepresent invention that when administered to a patient ameliorates asymptom of atherosclerosis or inflammation.

The compounds of the present invention can be administered to a patienteither alone or as part of a pharmaceutical composition. Thecompositions can be administered to patients either orally, rectally,parenterally (intravenously, intramuscularly, or subcutaneously),intracisternally, intravaginally, intraperitoneally, intravesically,locally (powders, ointments or drops), or as a buccal or nasal spray.

Compositions suitable for parenteral injection may comprisephysiologically acceptable sterile aqueous or nonaqueous solutions,dispersions, suspensions or emulsions and sterile powders forreconstitution into sterile injectable solutions or dispersions.Examples of suitable aqueous and nonaqueous carriers, diluents,solvents, or vehicles include water, ethanol, polyols (propyleneglycol,polyethyleneglycol, glycerol, and the like), suitable mixtures thereof,vegetable oils (such as olive oil), and injectable organic esters suchas ethyl oleate. Proper fluidity can be maintained, for example, by theuse of a coating such as lecithin, by the maintenance of the requiredparticle size in the case of dispersions and by the use of surfactants.

These compositions may also contain adjuvants such as preserving,wetting, emulsifying, and dispensing agents. Prevention of the action ofmicroorganisms can be ensured by various antibacterial and antifungalagents, for example, parabens, chlorobutanol, phenol, sorbic acid, andthe like. It may also be desirable to include isotonic agents, forexample sugars, sodium chloride, and the like. Prolonged absorption ofthe injectable pharmaceutical form can be brought about by the use ofagents delaying absorption, for example, aluminum monostearate andgelatin.

Solid dosage forms for oral administration include capsules, tablets,pills, powders, and granules. In such solid dosage forms, the activecompound is admixed with at least one inert customary excipient (orcarrier) such as sodium citrate or dicalcium phosphate or (a) fillers orextenders, as for example, starches, lactose, sucrose, glucose, mannitoland silicic acid, (b) binders, as for example, carboxymethylcellulose,alginates gelatin, polyvinylpyrrolidone, sucrose, and acacia, (c)humectants, as for example, glycerol, (d) disintegrating agents, as forexample, agar-agar, calcium carbonate, potato or tapioca starch, alginicacid, certain complex silicates, and sodium carbonate, (e) solutionretarders, as for example paraffin, (f) absorption accelerators, as forexample, quaternary ammonium compounds, (g) wetting agents, as forexample, cetyl alcohol and glycerol monostearate, (h) adsorbents, as forexample, kaolin and bentonite, and (i) lubricants, as for example, talc,calcium stearate, magnesium stearate, solid polyethylene glycols, sodiumlauryl sulfate, or mixtures thereof. In the case of capsules, tablets,and pills, the dosage forms may also comprise buffering agents.

Solid compositions of a similar type may also be employed as fillers insoft- and hard-filled gelatin capsules using such excipients as lactoseor milk sugar as well as high molecular weight polyethyleneglycols, andthe like.

Solid dosage forms such as tablets, dragees, capsules, pills, andgranules can be prepared with coatings and shells, such as entericcoatings and others well-known in the art. They may contain opacifyingagents, and can also be of such composition that they release the activecompound or compounds in a certain part of the intestinal tract in adelayed manner. Examples of embedding compositions which can be used arepolymeric substances and waxes.

Biological Examples

Rabbit Reticulocyte 15-LO Assay (h15LO)

The present 15-LO assay takes advantage of the ability of 15-LO tooxidize the fatty acid linoleic acid to the hydroperoxy fatty acid13-(S)HPODE, resulting in the formation of a conjugated diene. The 15-LOinhibitors are incubated with 15-LO enzyme in the presence of linoleicacid substrate. The initial reaction is compared to an uninhibited(maximal) reaction to yield % inhibition. The 13-(S)HPODE produced inthe reaction is reduced to the more stable corresponding hydroxy fattyacid, 13-hydroxyoctadecadienoate (13-HODE). This prevents artificialnonenzyme lipid peroxidation and product breakdown in the sample.13-HPODE is quantitated by comparing peak areas of individual sampleswith those from a standard curve generated using authentic 13-HODE. Thisassay is performed using 2U of rabbit reticulocyte 15-LO in the presenceof 174 μM linoleic acid. The reaction is incubated for 15 minutes at 4°C. The total reaction volume is 100 μL in PBS containing 0.2% Nacholate. The reaction is stopped with 100 μL of mobile phase and 10 μLof triethyl phosphite, which reduces the 13-HPODE to the more stable13-HODE.

Fifteen-lipoxygenase was obtained from phenylhydrazine-treated rabbitsand purified per the method of Rapoport (Rapoport S. M., Schewe T.,Wiesner R., et al. The lipoxygenase of reticulocytes. Purification,characterization, and biological dynamics of the lipoxygenase; itsidentity with the respiratory inhibitors of the reticulocyte. EuropeanJournal of Biochemistry, 1979;96:545-561). The following chemicals werepurchased and used as received: linoleic acid (NUJCheck Prep), 13-HPODE(Biomol Research Labs), sodium cholate (Sigma), trimethyl phosphite(Fluka Chemicals).

Monocyte Recruitment Assay

The recruitment or chemotaxis of monocytes was assayed by methods wellknown to those skilled in the art. In particular, the method set forthin J. Clin. Invest., 1988;82:1853-1863, which is hereby incorporated byreference, was used.

Synthetic Examples

The compounds of the invention which are diarylamines can be prepared byreacting an aminobenzanilide with an appropriately substitutedtriarylbismuthine in a solvent such as ether, tetrahydrofuran,dichloromethane, chloroform, or the like. The reaction time is 1 hour to96 hours, generally 4 hours, at a temperature from 20° C. to 70° C.,preferably 40° C. to 50° C., in the presence of an organic base and acopper salt. The organic base can be chosen from any of a number such aspyridine, DABCO, DBU, trialkylamine, diisopropyl-ethylamine, etc.,preferably triethylamine. The copper salt can be a copper(I) orcopper(II) species, or even copper itself, but is preferably copper(II)acetate. The reaction requires at least a stoichiometric amount of eachof the reagents but they may be employed in large excess; typically anapproximately equimolar amount of each is employed. The triarylbismuthreagents may be triaryl Bi(III) or Bi(V) compounds, the latter beingalso the dihalo- or diacyl-species, with thetris(substituted-phenyl)bismuthines being preferred.

The required triarylbismuthines are either commercially available orprepared from commercially available materials using methods known inthe literature, for example by reacting a Grignard reagent with Bi(III)chloride in THF.

Alternatively, the compounds of this type can be prepared by thewell-known Ullmann reaction, in which an amino-benzanilide is reactedwith an appropriately substituted aryl halide, such as a bromo- oriodobenzene in the presence of a base such as potassium carbonate orsodium carbonate or an organic base like N-ethylmorpholine, and a coppersalt as described above, in a high-boiling solvent such as xylene,toluene, mesitylene, DMF, or DMA. The reaction is typically carried outat a temperature between 100° C. to 200° C., preferably 150° C. to 160°C. The concentrations of the reagents is not critical; typically a 2- to5-fold excess of the reagents relative to the benzanilide is utilized,and the reaction time extends from 3 hours to 5 days, depending on thesubstituents present on the aromatic rings.

The aminobenzanilides required are either commercially available or areprepared by methods well-known in the chemical literature.

The thioureas of this invention may be prepared in various ways, all ofwhich are well-known in the art. A convenient method of preparing thethioureas in this patent is to react a substituted aminobenzanilide witha substituted phenylisothiocyanate in a nonpolar aprotic solvent such asTHF, ethyl acetate, ether, dichloromethane, or dioxane for from about 2hours to 3 days at from about 0 degrees to about 70 degrees. Theresulting product is collected by filtration or is obtained byconcentration of the reaction mixture and then collected by filtration.

Isothiocyanates of various types are well-known and widely available topractitioners of the art.

The sulfonamides of this invention can be prepared using procedureswell-known in the art. In a typical preparation, an aminobenzanilide isreacted with a sulfonyl chloride in equimolar proportions either neat orin a nonreactive organic solvent such as dichloromethane,tetrahydrofuran, toluene, dioxane or the like in the presence of a basesuch as trialkylamine, pyridine, DABCO, or DBU, over a wide range oftemperatures typically from 0 degrees to about 150 degrees and a timeperiod of 5 minutes to 5 days, followed by a workup procedure well-knownto practitioners of the art. The molar ratios of the reactants are notcritical but for the compounds of this invention equimolar ratios arepreferred. Likewise, the sulfonamides of this invention are preferablyprepared using pyridine as solvent with a reaction time of approximately3 days at room temperature.

The required sulfonyl chlorides are in general commercially available orare readily prepared by methods well-known in the chemical literature.

In Vivo Tests-Methods

Biochemical Methods

The entire descending thoracic aorta was assayed for its cholesterylester (CE), free cholesterol, and total phospholipid content. The lipidswere extracted in chloroform:methanol (2:1) by the procedure of Folch,et al. Folch J., Lees M., Sloane-Stanley G. H., A simple method for theisolation and purification of total lipids from animal tissue, J. Biol.Chem., 1957;226:497-509) and 300-500 μL of an internal standard, i.e.,200 mg/ml solution of 4-hydroxy-cholesterol in ethyl acetate:acetone(2:1), was added to the extracts of the thoracic aortic samples. Afterextraction, the organic phase was dried under nitrogen and redissolvedin isooctane/tetrahydrofuran (97:3). The lipid content and compositionof the thoracic aorta were measured using an HPLC method.

Cytochemical Methods

For histologic evaluation of the aortic arch lesions and forquantification of aortic arch cross-sectional lesion area, a 1 cmsegment of the ascending aorta distal to the aortic valves was fixed in10% neutral buffered formalin for 24 hours. The vessels were dehydrated,cleared in xylene, and infiltrated with molten paraffin (<60° C.) usinga Tissue Tek VIP autoprocessor (Miles Scientific, Elkhart, Ind.). Thetissue segments were embedded in paraffin and sectioned at 5 μm with aReichert-Jung microtome (Baxter, McGraw Park, Ill.). In order to obtaina thorough representation of the histologic appearance of the aorticarch lesions, 3 ribbons of 20 sections each were cut. Each ribbon ofsections was spaced approximately 100 μm apart. Three pairs of sections,i.e., 1 pair from each ribbon, were affixed to cleaned3-aminopropyltriethoxy-silane coated glass slides and stored untilstained. The general histologic character was evaluated in Verhoeff'selastica stained sections.

Morphometric Methods

The gross extent of atherosclerosis within the aortic arch was measured.In addition, sections of the aortic arch, a site ofhypercholesterolemia-induced lesions, stained using the Verhoeff'selastica procedure were used for quantification of lesioncross-sectional. The internal elastic lamina (IEL) was indentified as ablue-black ring and images of that region were collected using a digitalcamera. The area within the IEL was quantified using the Image Pro Plusimage analysis software. The area of the lumen of the aortic arch wasalso quantified in a similar fashion. Lesion area was defined as thedifference between the area circumscribed by the internal elastic laminaand the lumen area.

Aortic arch lesion extent was also measured. The area distal to the 1 cmsegment taken for histologic evaluation to the first intercostal ostiawas removed from the animal, opened longitudinally and images of thesurface of the vessel was collected using a digital camera. The lesionswere identified as raised, opaque areas and their area was determinedusing the Image Pro Plus image analysis software. The area of the entireaortic arch was also determined. The percentage of aortic arch coveredby atherosclerotic lesions was calculated.
